What does this test do? This is a home-use test kit to measure the pH of your vaginal secretions. What is pH? pH is a way to describe how acidic a substance is. It is given by a number on a scale of 1-14. The lower the number, the more acidic the substance.What type of test is this? This is a quantitative test -- you find out how acidic your vaginal secretions are.Why should you do this test? You should do this test to help evaluate if your vaginal symptoms (i.e., itching, burning, unpleasant odor, or unusual discharge) are likely caused by an infection that needs medical treatment. The test is not intended for HIV, chlamydia, herpes, gonorrhea, syphilis, or group B streptococcus.

How accurate is this test? Home vaginal pH tests showed good agreement with a doctor's diagnosis. However, just because you find changes in your vaginal pH, doesn't always mean that you have a vaginal infection. pH changes also do not help or differentiate one type of infection from another. Your doctor diagnoses a vaginal infection by using a combination of: pH, microscopic examination of the vaginal discharge, amine odor, culture, wet preparation, and Gram stain.Does a positive test mean you have a vaginal infection? No, a positive test (elevated pH) could occur for other reasons. If you detect elevated pH, you should see your doctor for further testing and treatment. There are no over-the-counter medications for treatment of an elevated vaginal pH.If test results are negative, can you be sure that you do not have a vaginal infection? No, you may have an infection that does not show up in these tests. If you have no symptoms, your negative test could suggest the possibility of chemical, allergic, or other noninfectious irritation of the vagina. Or, a negative test could indicate the possibility of a yeast infection. You should see your doctor if you find changes in your vaginal pH or if you continue to have symptoms.How do you do this test? You hold a piece of pH paper against the wall of your vagina for a few seconds, then compare the color of the pH paper to the color on the chart provided with the test kit. The number on the chart for the color that best matches the color on the pH paper is the vaginal pH number.Is the home test similar to your doctor’s test? Yes. The home vaginal pH tests are practically identical to the ones sold to doctors. But your doctor can provide a more thorough assessment of your vaginal status through your history, physical exam, and other laboratory tests than you can using a single pH test in your home.Useful Links
